How to Set COI Expiration Reminders
By Keelstar Team · Updated July 11, 2026
The short answer
Set COI expiration reminders at 60, 30, and 7 days before each policy line expires — general liability, automobile, workers compensation, and umbrella renew on different dates and need separate alerts. Route reminders to the vendor, their broker, and your internal owner for that vendor relationship. Tie the final reminder to a consequence: site access suspension, invoice hold, or removal from approved vendor lists. Spreadsheet date columns fail at scale; use a tracker that stores each policy expiration independently and logs outreach. Construction projects should align reminders with subcontract compliance meetings; healthcare systems should align with annual vendor recredentialing cycles. Reminders only work when someone acts on them — assign owners, not distribution lists.
Track each policy line separately
A single vendor may have four different expiration dates on one ACORD 25. Configure reminders per line — not one reminder per certificate. Operations teams get burned when GL renews but workers comp lapses unnoticed because only the certificate issue date was tracked.
Standard reminder cadence
Adopt a consistent schedule across construction, property, and healthcare portfolios: 60-day advisory, 30-day action required, 7-day final notice with access or payment consequence. Document sends in the vendor record.
- 60 days: email vendor and broker with expiration date and required limits
- 30 days: second notice; flag internal owner
- 7 days: final warning; prepare access block
- Day after expiration: suspend until renewed certificate received
Assign internal owners
Reminders to a shared inbox get ignored. Assign each vendor or project tier to a compliance coordinator, project accountant, or property manager who confirms follow-through. Construction supers need expired-sub reports before weekly safety meetings.
Integrate with renewal workflow
Expiration reminders should trigger a renewal request template listing your current requirements — not a generic 'your COI expired' message. Include certificate holder address and endorsement requirements so brokers return compliant certificates on first resubmission.
Escalation when reminders fail
If no response by expiration, execute your enforcement policy: stop work order, badge deactivation, or AP hold. Escalate to procurement and risk for vendors continuing to perform without valid coverage. Document enforcement for owner and payer audits.
Measure reminder effectiveness
Track percentage of vendors renewed before expiration, average days overdue, and count of access blocks required. Rising overdue rates signal broker relationship problems or requirements too burdensome to meet — both deserve management attention before a claim occurs.
Frequently asked questions
- How far in advance should we remind vendors about COI expiration?
- First notice at 60 days gives brokers time to process renewals and endorsements. Second at 30 days and final at 7 days. High-risk construction subs may need 90-day lead time when additional insured endorsements are required.
- Should reminders go to the vendor or the broker?
- Both. Email the vendor contact and copy the producer listed on the ACORD 25. Brokers often control renewals; vendors may not know their GL expired until you tell them.
- What if only one policy line expires?
- Alert on that specific line. A vendor with current workers comp and expired GL still cannot work on most sites. Partial compliance is non-compliance for the expired line.
- Can calendar reminders replace a COI tracker?
- Calendar invites do not scale across hundreds of vendors and multiple policy lines. Use a system that tracks expirations per vendor per line and automates reminder sequences.
